Objective To investigate the current situation of nursing research based on Omaha system in China. Methods All the nursing research based on Omaha System were retrieved and collected by using China National Knowledge Infrastructure, Wanfang database and VIP database, NoteExpress software for the management of documents was used. Based on the classification of nursing research literature, a content analysis of system analysis model analyzed the documents had been retrieved. Results Sixty-four pieces of literature were included, and thirteen categories system were formed. The transverse reliability coefficient of all kinds of system were 0.940-1.000, the longitudinal reliability coefficient were 0.658-1.000. Conclusions The study of nursing research based on Omaha system in China is booming, which is also facing challenges, and has a broad space for exploration.

To discuss the etiology, pathogenesis, therapies and prescriptions of psycho-cardiological abnormality of patients with coronary heart disease. According to the advance in modern diagnosis and treatment, the authors believed that psycho-cardiological abnormality of patients with coronary heart disease is closely related with mental stresses, like anxiety, depression and insomnia. It is mostly caused by emotional injury and expressed in heart, liver, spleen and kidney. The pathogenesis is heart-liver hyperactivity, yin deficiency in heart and kidney, and insufficiency in heart and spleen. The full recognition of etiology and pathogenesis of psycho-cardiological abnormality of patients with coronary heart disease and the combined treatment of disease and syndromes are of great significance to reduce mental stress and other risk factors, prevent and treat coronary heart disease and improve prognosis.

This study was aimed to observe the effects of Gui Curcuma extract on proliferation, collagen production, and matrix metalloproteinase (MMP) expression by hepatic stellate cells (HSC-LX2). HSC-LX2 were cultured in DMEM broth (10% FBS), then treated with Gui Curcuma extract (with the concentration of 0, 22.5, 45, 90 μmol·L-1) for 24 h. The proliferation of HSC-LX2 was measured by MTT assay; injury in HSC-LX2 was indicated with LDH re-lease; collagen I production was detected by ELISA; and MMP-l expression was determined by Western blot. The re-sults showed that Gui Curcuma extract (with the concentration of 22.5, 45, 90 μmol·L-1) dose-dependently inhibited proliferation of HSC-LX2 by 16.2%, 43.9%, 59.4% in MTT assay, respectively. The IC50 was 59.1 μmol·L-1. There was no significant impact on LDH release. The Gui Curcuma extract (with the concentration of 45, 90 μmol·L-1) can significantly reduce the expression of collagen I level (P< 0.01), whereas MMP-1 expression was significantly uplift-ed (P< 0.05) by Gui Curcuma extract (with the concentration of 45, 90 μmol·L-1) in Western blot. It was concluded that Gui Curcuma extract had the potential to prevent hepatic fibrosis, through inhibiting proliferation and collagen I production, and increasing MMP-1 protein expression.

Lots of studies implicate that pathological high-frequency oscillation (HFO) was associated with epilepsy. In recent years, new recording technologies have advanced such that, at high temporal and spatial resolutions, high-frequency oscillation can be recorded in partial epilepsy by intracranial electrodes. More and more researchers focus on the study of high frequency oscillation. The techniques, which were used to record, automatic mine, analysis and quantify high-frequency oscillation, are develop quickly. As a new biomarker of epilepsy, high-frequency oscillation can reflect the epileptic form activity. The HFO has a great value in localization of human epileptic brain and epilepsy surgery.

Objective To dump and recover the expired data in No.1 Military Medical Project, avoiding the waste of large amount of storage space and improving the operation performance of hospital information system. Methods After clearing the backup table, the data from the original table backup was put into the backup table. The data was unloaded from the backup table to a file, and then the file was saved. The data in the original table was deleted, but it could be restored to the table when needed, and the corresponding data could be obtained through the application program. Results The storage space was enlarged after data dump. Conclusion The dump of the expired data can make data management more scientific and hospital information system run more smoothly.

Objective:To enhance the ability of organizing, commanding, decision-making and contingency-meeting of campaign medical support commanding officers so as to qualify them for their positions by simulation training. Methods: Based on the decision support theory, modern medical support theory, health service optimized decision support system and medical support command simulation training system, we designed and constructed a simulation training platform for medical support decision optimization. Results: A network-based simulation training platform was successfully constructed, which gives a strong support to the simulation training in medical support decision optimization under the network circumstance. Conclusion: The application of the simulation training platform has enriched the content and renewed the pattern of training in decision optimization for campaign medical support commanding officers.

The concept of EMR is described and the problems of EMR application are analyzed including restrictions on change permissions and writing time of EMR, and sounds in medical record management mechanism to ensure legality and effectiveness of record. Based on improvement of national policy, third-party management services institutions are estab- lished and related suggestions on technical and environmental support of EMR development are provided, and the future of its development in our country are expected.

Polyethylene glycol(PEG) with good hydrophilicity and flexibility can improve pharmacokinetic and pharmacodynamic properties of the nano-preparation,so PEG modification in the surface of nano-preparation can increase the in vivo residence time and concentration of drugs.At present,the targeted nano-preparation with PEG modification has become a research hotspot in the field of pharmaceutics.In this paper,the physical and chemical methods of PEG modification in targeted nano-preparation was summarized,which includes physically inserting PEG-lipid derivatives in nanostructure of targeted nano-preparation or modifying PEG with targeted nano-preparation.In addition,the influence of PEG parameters (molecular mass,modified density and spatial conformation) on properties of targeted nano-preparation was also discussed,which is important to preferably structure PEGylated targeted nano-preparation.

Objective To study the signal transduction pathway of norepinephrine (NE)-induced expressions of oncogenes c-fos and c-myc in the rat heart. Methods mRNA levels of c-fos and c-myc in the left ventricle of the Langendorff-perfused rat heart was quantitated by reverse transcription and polymerase chain reaction (RT-PCR). Results NE increased the expressions of c-fos and c-myc while the effects of NE on the expressions of c-fos and c-myc were blocked by ? 1-adrenergic blocker prazosin (5?10 -6 mol/L) completely. Neomycin (5 mmol/L) and ruthenium red (10 ?mol/L) decreased the NE-induced c-fos and c-myc mRNA levels. Conclusion NE can induce the expressions of oncogenes c-fos and c-myc in the ventricle mediated by ? 1-adrenergic receptor. The signal transduction pathway of NE-induced c-fos and c-myc expressions may be associated with inositol phosphates-Ca 2+ system and diacylglycerol-protein kinase C system.
